UMBILICUS TROPAEOLIFOLIUS BOISS (CRASSULACEAE) A NEW RECORD TO THE FLORA OF THE ARABIAN PENINSULA

The plant diversity Sowth West of the Arabian Peninsula is considered to be very high due to its location, variation of climates, and geographical features. Generally, the Arabian Peninsula characterized by a very rich flora and is still not explored well. During the field survey of rare plant species, the authors collected a specimen of new taxa from the remote and inaccessible habitats in Jabal Ibrahim of the Asir region, Saudi Arabia. The plant was not reported so far in the flora of the Arabian Peninsula. The present paper deals with the record of one new plant species (Umbilicus tropaeolifolius Boiss) to the flora of Saudi Arabia and the Arabian Peninsula. The plant has a very small population range and very limited occupancy. The plant specimen was collected and later on identified and described with the available flora reference and with contact of a botanist.
